Please tell me what I'm doing wrong.
Nothing is wrong, and everything is working as expected.
Jetway lined up at door left 2
That's because, as I've said, the
default FSX jetway animation system, which is what KORD (and all our sceneries, except KMEM and KIAH, which use SODE) uses, will automatically, and totally outside our control, move the jetway towards the main passenger door
as defined in your airplane.cfg.
This means, if your airplane.cfg has been made with the 2nd door configured to be the main one, the jetway WILL go there, regardless of GSX. The default GSX jetway will only look at the [Exits] section of the aircraft.cfg, and neither GSX or the scenery has any control over this.
Since GSX,
by default, expect to open the 1st door, it will wait for it in any case. But of course, you can
configure GSX, to set the 2nd door to be the first passenger door, and this is done by swapping the data for the doors 1 and 2 with the included airplane configuration editor.
Exchange all their parameters, including the custom XML expression and the custom name in the editor. Your goal is to have what is now Exit 2L to go into the GSX Passenger Door #1 slot, and vice-versa. Exit 1L should then go into GSX Passenger Door #2 slot.
